JOHN EWASEN, OF MOSCOW, IDAHO.

PLOW.

Application filed February 24, 1923. Serial No. 625,662.

T 0 all 10 7mm it may; concern Be it known that I, JOHN EwAsnN, a subject of the King of Great Britain, residing at Moscow, in the county ofLatah and State of Idaho, have invented a new and useful Improvement inFlows, of which the following is a specification.

My invention consists of a separable and detachable plow for use on anysuitable plowbeam to which it may be properly secured.

My object is to pr vide a plow head that may be readily detached fromthe plowbeam for alteration or repairs, and in which the worn parts maybe easily and cheaply removed and replaced by new ones without sacrificeof the body portion.

How I attain my object will be readily understood from a perusal of thefollowing, and a study of the accompanying drawings, of which Fig. 1 isa plan view of the body portion, commonly called a shoe, and comprisingan upright portion called a shank, and a horizontal portion called a.frog. Fig. 2 is a side view of the same, Fig. 3 is a rear view, and Fig.4 is a front view. Fig. 5 is a plan view of the device showing theplowpoint and shares in place on the frog, whilst Fig. 6 is a side viewshowing the same bolted to the shank of a plowbeam.

More in detail, the upright porti! 1' of the shoe, the shank 1, has avertical slot or channel 2 longitudinally through its rear for thereception of the plowbeam 3 to which it is to be attached, and has ahole 4: (or a series of holes) transversely through its sides and reistering with a corresponding hole (or holes) through the plowbeam shankfor the insertion of the bolt 5 (or bolts) by whichit is securedthereto.

The frog 6 is a broadly flaring, triangular, and approximatelyhorizontal portion sloping downwardly both forwardly and laterally fromthe lower end of said shank 1, and integral therewith, and broad at therear, and tapering rapidly to a point at the front where the slopingsides intersect in the ridge 7. These sloping sides have portionsextending rearwardly of said shank, forming wings 8 and giving anarrow-head appearance to the shoe. A diamond-shaped plowpoint 9 isfitted as a saddle on the ridge 7 and is sezured thereto and to the noseof the shoe by bolts or screws 10. Abutting said plowpoint, one oneither side thereof, a pair of rectangular blades or shares 11 aresecured at then forward ends to the sloping sides of the frog, and attheir rearward ends to the wings 8, by means of the bolts or screws 12.

Bolts and screws being parts readily removable. it will be evident thatthe shoe may be easily detached from the plowbeam and from the plowpointand shares.

Having thus described my invention, I claim the following as new andpracticable, and pray that Letters Patent be granted me thereon:

1. In a plow having a beam wit-h a downwardly projecting shank, adetachable shoe secured to said shank by suitable bolts, and comprisingan upright portion or stem having a longitudinal and approximatelyvertical slot through its rear for the reception of said shank, andterminating at its lower end in a substantially horizontal andtriangular base portion or frog sloping downwardly therefrom bothforwardly and laterally, and terminating in a ridge at its front, adiamond-shaped plowpoint saddled on said ridge and removably securedthereto, and a pair of rectangular shares similarly secured to thesloping sides of said frog and to the rearwardly extending wingsthereof, and having their forward ends abutting against said plowpoint.

2; A plow comprising a beam, a substantially horizontal and flatbottomed shoe depending from said beam, triangular in shape, andprovided with a vertical shank having a longitudinal slot in its rearfor the reception of said beam, means for i'emovably securing said shankto said beam, downwardly and laterally sloping sides on said shoe,converging to a point at its front and forming an obtuse ridge at theirintersection, and having wing portions at their rear ends extendingobliquely and diver gently rearward of said shank, a substantiallydiamond-shaped plowpoint saddled on said ridge and said point of saidshoe, and secured thereto by removable means, and a pair of rectangularshares obliquely mounted on said sides and said wing portions byremovable means, and having their forward ends abutting against saidplowpoint.

JOHN EWASEN.
